Whisk together all of the ingredients in a mixing bowl.

Add a rack to the bottom of the Crockpot, or create one using balls of tin foil.

Pour the mixture into a well greased small casserole dish.

Place the dish on the rack in the Crockpot, and add water until it comes about halfway up the side of the dish.

Close the lid and cook on low for 4-6 hours until the mixture has set.

Let cool and then serve, or chill before serving if desired.
